The Thursday afternoon keynote was given by Ross Mauri of IBM. IBM has become a large supporter of Linux and open-source. Of course, this is because IBM has moved away from software sales and is focused mainly on services and hardware now (grin).
There used to be a saying that no one got fired by buying from IBM, so to see this company embracing Linux is encouraging. Ross pointed out that the first LWE he attended was dominated by geeks with few (he said four) business customers. This one is very commercial, with names like Oracle, IBM, Novell, Intel and others in attendance.
I also attended a talk by Maria Winslow who has been doing some serious work on the financial benefits moving to open source. OpenNMS was mentioned in a case study, so Go Team.
